Alicain Carlson and John Dole published a study in the October 2015 issue of HortTechnology that can help pineapple lilies gain favor with cut flower growers, and may spark interest among floral consumers.http://phys.org/news/2015-12-optimal-conditions-pineapple-lily.html

In their study for GEOLOGY, published online on 28 Aug. 2014, researchers Camilla Crifò and colleagues used leaf vein density, a trait visible on leaf compression fossils, to document the occurrence of stratified forests with a canopy dominated by flowering plants.http://phys.org/news/2014-09-life-fossil-canopy.html

A transportable ion trap developed at MPIK was used for generation and storage of the ions. The high-precision measurements provide important new insight into the role of highly charged ions in astrophysical plasmas, e. g. for radiation transport inside stars.http://phys.org/news/2013-09-iron-sun-greenhouse-gas-x-ray.html
Astronomy Fri, 06 Sep 2013 08:37:39 ESTnews297675449Using math models to make predictions: How vegetation competes for rainfall in dry regionsThe greater the plant density in a given area, the greater the amount of rainwater that seeps into the ground. This is due to a higher presence of dense roots and organic matter in the soil. Since water is a limited resource in many dry ecosystems, such as semi-arid environments and semi-deserts, there is a benefit to vegetation to adapt by forming closer networks with little space between plants.http://phys.org/news/2013-08-math-vegetation-rainfall-regions.html

Engineering Mon, 25 Jun 2012 13:20:01 ESTnews259848462How does a plant survive with few mates or pollinators? A European herb has figured out its own wayIn plants that rely on animals for pollination, the number of seeds they produce, or their relative fitness, is influenced by pollinator visits and the successful deposition of pollen. The number of visits a plant may receive depends partly on pollinator density as well as on conspecific plant density. But what if a plant happens to grow in a population that is small or has very few pollinators visiting its flowers? Will all the effort put into flowering and attracting pollinators have gone to waste? Some plants, including a bright pink, short-lived, western European herb, have found a way to ensure their future reproductive fitness despite such limitations.http://phys.org/news/2011-11-survive-pollinators-european-herb-figured.html

They suggest that this increased the amount of water available to the leaves, making it possible for plants to capture more carbon and grow larger. A better plumbing system may also have radically altered water and carbon movement through forests, driving environmental change.http://phys.org/news/2011-05-rainforests-arose-plumbing-problem.html
